In several states, bridge deck delamination of reinforced concrete bridge decks built with partial-depth-precast (PDP) concrete panels and cast-in-place decks has been observed. The PDP panels are typically prestressed. Recently, one such failure was observed in the Utah. There is a need to develop strengthening and repair methods to re-laminate the precast concrete panel and cast-in-place deck, ensure composite behavior through mechanical connections, or strengthen the panel such that bridge deck delamination does not pose a safety risk. The goal of the study is to develop numerical models to predict the response of structurally delaminated concrete decks and the response of strengthened decks.
